Which tools translate programming code into machine language or execute code?

• A. Compiler
• B. Assembler
• C. Interpreter
• D. Interpreter and compiler

Answer: (D)

Understanding how code becomes something the computer can run involves two main approaches: translating code into machine language ahead of time, and executing code directly. A compiler takes high-level code and turns it into machine language before the program runs, producing an executable. An interpreter, by contrast, reads and executes the code on the fly, performing the actions as it goes. Assemblers also translate from assembly language to machine code, but the prompt focuses on higher-level code and direct execution, so pairing interpreter with a compiler covers the two primary ways code is turned into something the machine can run. That’s why combining interpreter and compiler is the best fit here.
